Debabani Choudhury discusses opportunities and challenges for some of the key technological advances and approaches at GHz to THz frequencies that are now emerging as possible components for wireless solutions of the future.

Proliferation of diverse wireless communication services as well as anytime, anywhere connectivity are becoming a norm in our day to day life. Communications using Machine-To-Machine (M2M), Peer-To-Peer (P2P) approaches are set to be the major growth areas and require high co-ordination between different wireless nodes. There is a major consensus that new wireless services based on new ways of using wireless technologies will grow exponentially in next few years. The need for high bandwidth wireless applications has also fueled research into mobile communication systems capable of high data rate throughputs at short ranges. Researchers worldwide are working on various architectures including different variations of MIMO, MU-MIMO approaches to enhance the data rate. MM-wave and THz research communities are also projecting technologies for addressing the needs for ultra-high-data rate applications. Although some of the approaches look very interesting, implementation challenges remain for real usage cases.
